Learning Curve: changing colour

I’m quite pleased with how this transition looks, changing from red to white.

For the last stitch of red, instead of a single crochet, I did a slip stitch and then slip stitched into the next one as well and fastened off.

Then, with the white, I went back to the last stitch and slip stitched into it; then I put a single crochet in the next stitch, (the second slip stitch of the red.)

My thinking was that 2 slip-stitches equal a single crochet, with each colour dividing the stitch in two.

I know that there re many methods out there but I think I will continue with this one as it makes sense in my head and looks pretty good, in my opinion.

What is your preferred way? I can be swayed!!
